That frustration made me search for the perfect non-Allergenic soap.
Although my daughter had it birth, it wasn't diagnosed till 8 weeks.
And until we made a natural aromatherapy remedy, Surestop to Eczema it was tough going.
Initially, after much research, switching to 100% cotton, fragrance free cleaners & soaps, food modification, and changes around the house, I found she still had eczema outbursts every single time she had a bath with a soap.
I could not find any soap in stores, that wouldnt aggravate it.
After going through Aveeno, Cetaphil, Dove, Johnson & Johnson, Castille Olive oil and struggling through a Dozen others, for months, I stumbled on a soap that I never heard about in a website selling cotton diapers. (they no longer have the website, but I found them again here.)
I googled it for a couple of weeks, and was impressed enough to order it and to my pleasant surprise- IT DID NOT PRODUCE ANY ECZEMA OUTBURST.
I had found it!
Savon de marseilles Olive Oil & Sea Salt soap! Eureka!
Pic is of a 400g palm oil white soap cube, the green one was done to death ;)
I cut it into 4-5 pieces that I can grasp in my hand- "SA" is on the slightly used block and "ON" can just be seen on the block I've used little above a month.
Its too big to hold comfortably- or even uncomfortably, for that matter- so you just need to cut it. But its really hard, as soaps go, so this is how to cut it:
Microwave 10 seconds at a time, and cut with a heavy knife when its just a bit warm- too much heat will cause the soap to bubble & froth into a humongous mass and swell up 6-8 times its size.
While it can still be used as soap, it'll have an irregular, bubbled up shape, and definitely wont fit into your hand.
Overall, it lasts easily for 6-8 months, even more and the handmade savon is a great investment compared to anything else you could buy as eczema soap.
I havent used the factory versions, which look prettier, they are well cut- or the liquid savon de marseilles soap, but I'm guessing they wont last as long- please let me know if I'm wrong - or right.
The Lavender variety however, did cause some very mild outbursts, so I stuck to the Green (Olive) and White (maybe Palm/olive oil or only palm, the seller couldnt say).
Purple one in pic above, below the white. The white powdery coating is actually sea salt deposit and it is part of the soaps benefits. In use, it has a mild lavender smell, that doesnt stay on the skin but gives a pleasing experience, not drying at all, but I wouldnt call it extra moisturising for winter use.
